A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
Recovering access without your old device depends on your backup status. If you have a cloud backup, download the app on your new device and select Restore from backup or Begin Recovery.
If not, you must use alternative verification like SMS, email codes, or recovery codes. Since you cannot access the old device to generate codes directly, proceed with the following steps: Use Alternative Verification: When prompted for an authenticator code, click the "Try another way", "Don't have access to my app", or similar links on the login screen.
Cloud Restoration: If you use Microsoft Authenticator, tap Begin Recovery and sign into the personal Microsoft account used for backups. If using Google Authenticator, download the app, sign into your Google Account, and your synced codes will restore automatically.
Bypass via Recovery Codes: If you saved the alphanumeric backup/recovery codes when you first set up your accounts, enter one of these when asked for your 2FA code.
Account Recovery: If no backups or recovery codes are available, you will need to start the specific service’s account recovery process to prove your identity.
Contact IT or Support: For work, school, or corporate accounts, you must reach out to your organization's IT department to reset your multi-factor authentication.
If you'd like, tell me which specific app you are using (e.g., Microsoft, Google, Duo, or a password manager) and which service you are trying to log into (e.g., Microsoft, Google, a bank, a gaming account), so I can provide the exact recovery steps for your situation!
